چکیده

Phytohormones, including salicylic acid (SA) and jasmonic (JA) have the potential to ameliorate plant development tolerance deleterious effects of toxic metals like nickel (Ni). Therefore, current study was carried out evaluate SA JA's interactive effect on root antioxidative response two Alyssum inflatum Nyár. populations against Ni-toxicity. Two A. species under different Ni concentrations (0, 100, 200, 400 μM) were exposed alone or combined levels 50, 200 JA 5, 10 treatments. Results showed that high concentration (400 reduced roots fresh weight in both than control. However, external application individual + higher doses had ameliorated biomass by mitigating Ni-toxicity, especially NM population, comparison μM Ni. Under toxicity, JA, their combination, induced accumulation plants' roots. Moreover, alone, as well found be effective scavenging hydrogen peroxide improving activity superoxide dismutase, peroxidase, catalase, ascorbate peroxidase Overall, our results manifest use, treatments, restricting translocation shoot, accumulating roots, enhancing antioxidant defense systems.
